In accordance with the Federal Land Policy Management Act (FLPMA), through the land use planning process, the BLM is required to consider all available information in order to determine the mix of resource uses and protection that best serves the multiple-use and sustained-yield mandate. Under the FLPMA, the BLM has numerous authorities requiring the agency to maintain inventories of all public lands and their resources, including wilderness characteristics, and to consider such information during the land use planning process. Section 201 of the FLPMA requires the Secretary of the Interior to "prepare and maintain on a continuing basis an inventory of all public lands and their resource and other values." The BLM-Colorado River Valley Field Office (CRVFO) has identified and completed an assessment of BLM-managed lands with wilderness characteristics outside of existing Wilderness Study Areas (WSAs). This assessment includes all BLM public lands within the Colorado River Valley Field Office. BLM Manual 6310 - Conducting Wilderness Characteristics Inventory on BLM Lands provides the guidance from which CRVFO performed the wilderness characteristic inventory process.

Inventories of units/areas that may contain wilderness characteristics are constantly being updated with new information. Listed below are units that were found to contain wilderness characteristics since the Resource Management Plan analysis.

*Reference Guide: Unit Numbers may be different between Form 1 and Form 2. (Area Unique Identifier on Form 2 refers to number in 1979 inventory GIS shapefile. You may notice that this number may not match the previous page (Form 1) due to differences between thepaper records and the GISshapefile, but the number was not used in the analysis and does not change the results. )
